Big Brother 1

 is the first season of NJ's Big Brother, which premiered on October 8, 2017, and ended with a live reunion on November 13, 2017.

After 21 days, Kara K. was crowned the winner over Adam D. in a 4-3 Jury vote.

Production
The series was officially announced on September 20, 2017 at the reunion of the online game, Survivor: Battle Royale, which was also hosted by the series creator. Applications opened on September 21, 2017, and closed two weeks later on October 5. In total 22 people applied, 10 were cut from the casting, and the remaining 12 went on to become the houseguests competing in the game. The full cast of 12 were revealed on October 7, 2017, ahead of the October 8 premiere.

Each "week" (a cycle of 2-3 days) the houseguests compete for the title of Head of Household. The HOH must take on the responsibility of nominating two houseguests for eviction. The winner of the Power of Veto then has the ability to save one of the two nominees, forcing the HOH to name a replacement nominee, or they may choose not to use it. The final two nominees on the block at the end of each week must then face the votes of all their fellow housemates, excluding the HOH. The person with the most votes is evicted, with the HoH making the final decision in the event of a tie. Once only the final two houseguests remain, a jury of previously evicted houseguests cast their votes to decide the winner of Big Brother.
